** Description changed: [ Impact ] When the Nvidia 470 driver is used GTK 4 fails to render most text labels. [ Workaround ] Install a newer Nvidia driver using the 'Additional Drivers' app if you - can. Otherwise add GSK_RENDERER=gl to /etc/environment and reboot. + can. Otherwise add GSK_RENDERER=gl (or GSK_RENDERER=vulkan) to + /etc/environment and reboot. [ Test Plan ] 1. Install the Nvidia 470 driver on a system that supports it, being careful to ensure that Nvidia is the PRIMARY GPU of the system. So usually a desktop. 2. Open the Settings app and verify that all the icons in the side menu are visible. 3. Open Nautilus and verify that no file icons are missing their text labels. [ Where problems could occur ] Anywhere else in the rendering of GTK 4 apps. [ Additional information ] With nvidia driver, all GTK4 applications have label rendering issues. They are not refresh until passing the cursor over them, giving blank windows. The corner are white and not themed. Passing from one app scren to another one reproduces the issue. gnome-control-center or files, for instance, are blank by default. As suggested by seb128, exporting GSK_RENDERER=gl fixes the issue.
